This article reports the use of a customized surgical guide for simple and precise C-tube plate placement with minimized incision.
Patients who were planning to have orthodontic miniplate treatment because of narrow interradicular space were recruited for this study. A combined silicone and stainless steel wire surgical guide for the C-tube was fabricated on the cast model. The taller wire of the positioning guide is used to accurately start the incision. The incision guide-wire position is verified by placing the miniplate on the coronal horizontal wire to confirm that the incision will coordinate with the screw holes. Because the miniplate is firmly held in place, there is no risk of the miniplate anchoring screws (diameter, 1.5 mm; length, 4 mm) sliding on the bone surface during placement with a manual hand driver.
The surgical guide was placed on the clinical site, and it allowed precise placement of the miniplate with minimum incision and preventing from slippage or path-of-insertion angulation errors that might interfere with accurate placement.
Customized surgical guide enables precise planning for miniplate positions in anatomically complex sites.
本文报道了一种定制手术导板的应用，用于简单精确地放置C形管板，并使切口最小化。
招募因牙根间间隙狭窄而计划接受正畸微型钢板治疗的患者进行本研究。在石膏模型上制作了一种用于C形管的硅胶和不锈钢丝组合手术导板。定位导板较高的钢丝用于精确开始切口。通过将微型钢板放置在冠状水平钢丝上来验证切口导丝的位置，以确认切口将与螺孔对齐。由于微型钢板固定牢固，在使用手动螺丝刀放置时，微型钢板锚固螺钉（直径1.5毫米；长度4毫米）在骨表面滑动的风险为零。
手术导板放置在临床部位，它允许以最小的切口精确放置微型钢板，并防止可能干扰准确放置的滑动或插入路径角度误差。
定制手术导板能够对解剖结构复杂部位的微型钢板位置进行精确规划。
